Meta has acquired AI analytics startup Sundial, an acquisition announced on October 23, 2026. Co-founder Chandra Narayanan said in a LinkedIn post that he is rejoining Meta along with co-founder Julie Zhuo, Stanley Watt, Asa Levi, John Maier and other members of the team “to build the next generation of AI analytics tools and agents.”

Neither his announcement nor the Meta post he shared discloses a price or other financial terms.

Who joins and what they will do

Alex Schultz, Meta’s chief data officer, wrote in the post Narayanan shared that Narayanan will lead Meta’s data analytics tooling and agents work. Schultz described the people joining as Meta alumni and said the team brings “their AI analytics technology” with them.

Schultz was named Meta’s first chief data officer on July 1, 2026, after leading both marketing and analytics. In his announcement of that role, he said his focus would be changing how Meta “learns and makes decisions in the AI era,” from data foundations to AI-powered analytics, experimentation and research. He named Analytics Agent as the most widely used AI agent inside Meta.

Narayanan wrote that he left Meta nine years ago. He thanked Sequoia Capital, Conviction and 01A Advisors as investors, and thanked a team at OpenAI that he said “pushed us harder and further than almost anyone.”

What Meta wants from the deal

The shared post sets out three parts of what Meta’s analytics group is building:

  • Descriptive analysis that answers the company’s questions “before it thinks to ask them.”
  • Experimentation, in which AI proposes tests, ships them, explains the results and decides what to do next.
  • Alerting and monitoring that surfaces only the signals that matter, “at a token cost that makes sense.”

“AI has created effectively unlimited demand for insights, and we want to define the future of AI analytics,” Schultz wrote. He said that in internal surveys about eight in ten new hires rate Meta’s AI analytics tools as the best they have used. That is Meta’s own survey, not an independent measurement.

An acquisition aimed at people and internal tools

Both posts describe the deal in terms of a team joining Meta’s internal analytics work. Neither describes Sundial continuing as a product sold to outside companies, and neither gives a closing date or says what happens to Sundial’s existing customers. Customers of the service should look for direct notice from the company rather than rely on the announcements.

For early employees of an acquired startup, the questions that usually matter are how unvested options are treated and whether shares can be sold before or at the deal. Our explainers on employee stock options and vesting and tender offers for employees cover the terms to look for; the announcements do not say how Sundial equity was handled.
